e0“maize plants were subjected to different concentrations (0, 50, 100, and 250 µM) of the herbicide 2, 4-dichlorophenoxyacetic acid (2, 4-D)”
e1“seedlings exposed to the highest concentration of 2, 4-D exhibited stunted growth and a reduction in chlorophyll accumulation”
e2“Key parameters such as relative water content, relative growth rate, and net assimilation rate decreased (by 25%, 39%, and 35% respectively) under this condition”
